Answer 2

The correct answers will be option a,C2H6.

•Bromine+ CCl4 is used to test unsaturation.

•We have to add bromine with constantly stirring with CCl4.

If the orangish red colour of the solution disappears then it Indicates unsaturation.

•C2H4 has a double bond, C2H2 has a triple bond, C3H6 has a double bond.

All these compounds are unsaturated, therefore will decolourise the bromine-carbon tetrachloride solution.

•C2H6 is saturated compound, therefore it will not decolourise the bromine-carbon tetrachloride solution.
